What is the torque specification on the draw rods?
The draw rods on Peterson pumps should be tourqed to 80 in lbs. Notice it is in inch pounds not foot pounds. These should be checked on a regular basis as part of the bolt check on the car. Can I cap off an unused stage or tie two stages together? No. Capping off an unused stage will result in pump damage and possible engine damage due to pump failure. The gerotor section needs oil for lubrication of the rotating aseembly. Also you may not “tee” two lines together as this can result in oil not being scavenged correctly. Each scavenge stage needs to have its own separate line running to the engine.
